FSQC for Use with Magnetic Motor Starters or Contactors

FSQC units listed below operate in the same way as standard units but are intended only for

use with magnetic motor starters or contactors. (Wiring diagram 1)

Receptacles have leads for splicing to conductors from the load side of contactor. The switch

actuated by the plug is wired into the starter or contactor coil circuit and controls only this

circuit. The starter or contactor is energized only when the plug is fully inserted and rotated to

close the switch. Since the plug is inserted or withdrawn only when the switch is open, the

circuit cannot be made or broken under the load.

Plugs used are standard APJ units and special polarity units listed are recommended where

interchange with devices for other wiring systems is possible.

DBR Interlocked Arktite ®

Receptacles With Enclosed

Circuit Breakers

APJ/NPJ Arktite Plugs

Application:

DBR interlocked Arktite receptacles with

enclosed circuit breakers and APJ/NPJ

Arktite plugs are used:

to supply power to portable electrical

equipment such as motor-generator sets,

compressors, heating and cooling units,

conveyors, and similar equipment

in locations where hazardous dusts are

present, as in grain processing and handling

plants, chemical plants and certain food

processing industries

indoors or outdoors in damp, wet or

corrosive locations

Features:

Receptacles are mechanically interlocked

with circuit breakers to provide disconnect

means, short circuit protection and thermal

time delay overload protection.

Enclosures are compact and rectangular in

shape permitting close spacing.

For maximum safety, the spring door

receptacle at the bottom is mechanically

interlocked with the circuit breaker operating

mechanism. The circuit breaker cannot be

closed until the plug is fully inserted and the

plug cannot be withdrawn unless the breaker

is open.

Operating handles can be padlocked in

either ‘‘ON’’ or ‘‘OFF’’ positions. Breakers are

trip-free of the handles and will open under

short circuit or overload even if the handle is

locked in the ‘‘ON’’ position.

Enclosure is provided with a drilled and

tapped conduit opening at top center,

equipped with a threaded-in bushing. The

size furnished is 1 1 ⁄2, and removing the

bushing permits the use of a 2 conduit.

Interchangeability of Plugs

with Other Hazardous and

Non-Hazardous Location

Receptacles:

Plugs listed for use with DBR assemblies

are standard Arktite APJ/NPJ plugs. Other

standard APJ/NPJ and CPH plugs of the

same rating, style and number of poles may

be used with DBR receptacles, as well as with

DR receptacles listed in Section 2P and with

EBBR, EPC and EPCB receptacles listed in

Section 4P.

As a result, portable equipment suitable for

the locations and equipped with the proper

plug can be used with AR receptacles for

non-hazardous locations, with EBBR, EPC

and EPCB receptacles for Class I hazardous

locations, and with DR and DBR interlocked

receptacles for Class II hazardous locations.

CAUTION: To reduce the risk of ignition of

hazardous atmospheres, do not use plugs or

receptacles in Class II, Group F locations that

contain electrically conductive dusts.

Pressure connectors are standard. Crimp/solder type
